Introduction
One cannot create an extension for generated IDOC types, since the extension concept for ALE interfaces created by T-Code BDBG or BDFG does not run with extension types.
BAPIs are the standardized interfaces for ALE-supported communication. The IDOCtypes required for the ALE services can be generated from BAPIs. So, one can create their own BAPIs in the customer namespace and generate the associated BAPI-ALE interface.
In the process, the following objects are generated for a BAPI:
The generated ALE IDoc interface performs the following tasks:
Step By Step Procedure for Creating Generated IDOC
STEP 1: Create a new structure with the customer fields that are required under the IDOC type as shown below.
STEP 2: Create a new remote enabled function module which is responsible for generating IDOC through SE37 as shown below.
STEP 3: Once the function module is created we need to create a BAPI for the outbound processing. This is implemented as a Business Object’s (BO) method, and will utilize the outbound function module previously created.
Go to SWO1 transaction and create new Object as a copy of EQUI object as shown below. (We can also create a new object and a method. However in case we need methods of EQUI, we can just copy the Object)
STEP 4: Add new method to the Business Object created with the function module previously created as shown below and press .
STEP 5: Provide Method, Method name and Description and click on .
STEP 6: Do not make any changes here and just click on .
STEP 7: A confirmation popup comes up and select ‘Yes’ to continue.
STEP 8: Once the method is created, do not forget to make the method function API enabled. This is done as shown below. Double click on the method to get this popup.
Once this is done, notice a small green icon beside the method(). This indicates that the method is API enabled.
STEP 9: Now click on object and go to ‘Edit menu’ and select the release status as ‘To Implemented’ as shown below.
STEP 10: Save the object type with the confirmation that pops up on changing the Release type to Implemented.
STEP 11: Now click on object and go to ‘Edit menu’ and select the release status as ‘To Released’.
You will see a small tick beside object name as seen below on 'Release' which indicates the object is released.
STEP 12: Now click on method and go to ‘Edit menu’ and select the release status as ‘To Released’ as shown below. (Before doing this make sure that the Function module created is set to release.)
You will see a small tick beside method name as shown below on 'Release' which indicates the method is released.
STEP 13: Click on (Generate) once the above steps are completed successfully and Save.
STEP 14: Now, go to BDBG T-Code and provide the Object and Method names created as shown below and Click on (Create).
STEP 15: Provide message type and click on .
STEP 16: Provide name for IDoc type, Outbound function module and Inbound function module as required and click on .
Following is the result.
Click on the IDoc type to check the structure generated.
Generated Segment:
One important thing to note here is, we have to make sure that IDOC types and Generated Segments have to be set to release to ensure their visibility across systems.
Create a Distribution Model – BD64 as shown below (Add BAPI with the Sender and Receiver along with the Object and Method Created above).
Create a new model view.
Select the Model View created and Click on ‘Add BAPI’ and provide the Sender/Receiver and Object/Method details as shown below.
On adding the BAPI, the model view looks like as shown below.
After, this go to Environment-> Generate Partner Profiles. This will create an entry in Outbound parameters of Partner Profile.
